Hi, Iam a newbie at building led bike lights and I need some help with what materials should I use for my build. I need most of the help on deciding what led's, drivers and lenses. The rest I can figure out myself. (I found out that Iam very gifted with a soldering iron):ihih: What I would like out of my build is a 2-3hr battery life, 500-200 lumen output. Any suggestions would be much appreciated. Right now my set up is a Cygolite Rover II and a Topeak whitelite HP AA on the handlebars. I like it but I really need more light IMO. :madman: Sooo what do you guys have for me???
